均匀场域中工频电场畸变效应分析
Analysis of power frequency electric field distortion effect on uniform electric field
摘要
Abstract
The electric field sensor for the measurement of electric field in the space where the sensor probe will cause distortion in the vicinity,so it will affect the measurement of electric field accuracy. This paper uses the separation of variables method to calculate the electric field distortion caused by spherical sensor probe in uniform electric field,and detailed analysis of the 10 kV voltage,the spherical probe size,electrode material and the measuring electrode pole coupling caused the impact of electric field distortion. According to the induced voltage of sensor and the linear relationship between electric field strength, using the impact factor matrix to correct the electric field distortion. The result shows that the vicinity of the probe and the primary measuring electrodes and sub-electrodes measuring produce more serious distortion in the uniformelectric field. The average distortion rate is more than 27% ;however,after the impact factor matrix is used to correct the electric field distortion,the average error is about 4.47%. By analysis of the measurement of the electric field distortion with the spherical probe of sensor, it is conducive to reduce the impact of distortion on the electric field measurement and to improve the accuracy of field measurement.关键词
